WILLIAM MGOUBBIN, OF OHATHAM, ONTARIO, CANADA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 268,258, dated November 28, 1882.

v Application filed April 28, 1881. (No model.)

To all whom 'bt may concern Be it known that I, WILLIAM MOGUBBIN, a subject of Her Majesty the Queen of Great Britain, residing at Ohatham, in the county of Kent, in the Province of Ontario and Dominion of Canada, have invented a certain new and useful Improvement in Oar-Oouplings; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertaius to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is a side elevation. Fig. 2 is a longitudinal vertical section, and Fig. 3 is a side elevation with part of the draw-headbroken" away to show the inside working parts.

Similar letters of reference indicate corresponding parts in all the figures.

My invention relates to automatic car-couplings; and it consists in the improved constrnciion and combination of parts hereinafter more fully described, and particularly pointed out in the claim.

A is the draw-head, which has a flaring mouth, as usual, to facilitate the insertion of the link shown at D.

B is a weight having a shaft or axle, F, which is inserted through and works in oblong slots G, registering with each other in the sides of the draw-head, so as to give the shaft, with its weight, a limited play or movement in an up and down direction. At the outer end of shaft F is a lever 0r handle, E. The weight B projects through and plays in a slot in the roof of the draw-head, and is itself slotted in its forward part to admit of the insertion of the draw-bolt G. The latter is prevented from slipping out ofits slot in B by laterally-projecting studs or pins c-one on each side--which rest in notched lips I) projecting from the forward part of the weight. It follows that when the weight B is tilted back, by means of the lever E, into the position shown in Fig. 3, drawbolt 0 moves with it and will occupy the position shown in said figure, supported by the contiguous side of the weight, which is then. uppermost. This is the position which the parts occupy in coupling or uncoupling. In coupling,as thelink D, entering the draw-head, strikes part d of weight B, the latter is tilted into the position shown in Figs. 1 and 2, which brings the draw-bolt O intoan approximately Vertical position through the link, while the rounded part a of the weight, by impinging upon the inner end of the link, will hold this in a horizontal position. At the same time the slots G in the draw-head permit of sufficient play of the weight and its draw-bolt to enable the link to adjust itself to cars of different heights.

Having thus described my invention, 1 claim and desire to secure by Letters Patent of the United States- The combination ofthe draw-head A, having oblong registering side slots, G, slotted weight B, having notched lips b, shoulder d, and shaft F, provided with the handle E, and draw-bolt 0, provided with the retaining pins or stops 0, constructed and combined to operate substantially as and for the purpose herein shown and specified.
